Abstract
An activated carbon is modified to have bactericidal properties and/or an additional ability to remove heavy metals and other toxic substances. Said modified activated carbon is especially suitable for purifying drinking water and can be readily modified to be suitable for various regions with specific tap water impurities. Pursuant to the invention, activated carbon fiber is treated to adsorb a member of the group consisting of cations, anions, organic complex forming agents, surfactants, polyelectrolytes and organic bactericidal compounds.
